I have played quite a bit of mount and blade and was looking for another game where there isn't a main storyline that you have to follow to progress. I really like not being forced by games to take a linear path. And I guess I am also looking to play as a character, not as a god/distant ruler (I gues in trying to say I don't wanna play a civ/total war type game). Also looking for it to be on pc, playable without the interwebz

If you haven't tried it, Sid Meier's Pirates! is kinda what you're looking for. It feels a lot like Mount and Blade in most respects. You start off as lowly privateer and eventually can join up with one of 4 factions and rise through the ranks. There is a main storyline, but it's more like a sidequest and you can easily ignore the whole thing if you'd like.

It was one of favorite games when it first came out. You can pretty much play it however you want. You can be a pirate hunter and gain fame and glory that way, or be a badass pirate yourself and build up a fleet of ships by attacking anyone and everyone. You can dedicate your services to one nation (even one you didn't start as), specifically target one nation above the rest, or play all the sides against each other for your own gain. Very satisfying game.

Only downsides are that the gameplay can get repetitive at times and traveling can take a long time depending on your target.

Any of the fallouts are pretty good for freewandering, but certainly not indefinite/able to just play as a trader or similar.

It just depends on how much you object to there being a 'storyline' - most games have one to some extent, but in all of the ones mentioned (except fallout 3, imo) the vast majority of the game is fairly seperated from any sort of 'main' plot.

Let me save you the trouble. My personal favourite of the roguelikes is Dungeon Crawl: Stone Soup since it is quite a bit easier to get into than the others and it has tiles instead of being ASCII. It even has a tutorial! (Note, a lot of roguelikes don't)
